Ridley Scott’s post-apocalyptic science-fiction film The Dog Stars has opened below expectations in North America, taking $8 million in its first weekend. The result matters because the film reportedly cost $70 million and arrives amid weak reviews, increasing pressure on its international performance and subsequent box-office run.

Starring Jacob Elordi, Josh Brolin and Margaret Qualley, the adaptation of Peter Heller’s novel was projected to open in the low double digits but instead finished behind Spider-Man: Brand New Day and Coyote vs. Acme. It is expected to make about $20 million worldwide in its opening frame, while holding a 40% Rotten Tomatoes critics’ score; reviewers have praised aspects of its performances and imagery but criticised its pacing and narrative.
